  1. Re:Bikes are pathetic for MPG figures. on University of Wisconsin Wins FutureTruck Competition · · Score: 1

    I think we agree on the basic principle: the 2-wheeled vehicles sold today are, for various reasons, getting less mileage than what's physically possible. But you think that's illogical, I think that's logical (though regrettable).

    Oh, it's perfectly logical why motorcycles get such lousy mileage. Huge engines for the sake of acceleration on almost every "street" bike. Some of these bikes have more displacement in their engines than the 1.5L engine in my Civic, which is a bit excessive.

    No one does...just like no one needs an SUV to get groceries, unless you're on an Indian reservation or archaeological dig. But we have yet to limit SUVs to Indians and archaeologists, and we have yet to restrict bikes to legal speeds, and I don't think we ever will.

    Eh? What does speed have to do with fuel economy? Why do SUVs need to be limited to Indians and archaeologists buying groceries?

    Have you been on a scooter lately? While a 125cc machine is obviously not going to be in the left lane of a controlled-access highway, from a standing start a scooter can hold its own. And then there's the growing category of "super scoots" or "sport scoots," but then you lose the high mileage. Which brings us back to the original point:

    I've seen scooters lately. They're pretty much worthless on interstate highways, but work well in city traffic.

    Exactly!!! Bikes don't have better fuel economy or emissions because we don't ask them to. That's not what the public looks for in a bike. SUVs don't get high mileage either, but manufacturers are making token efforts to shut up protesters/the government.

    The public needs to start looking at bikes closer with regards to emissions. At the present time, a motorcycle is one of the worst vehicles to own as far as fuel economy and pollution are concerned.

    You (the public) can't bitch and moan about SUV makers who have 5000 pound vehicles that get 20mpg, when the average "performance" street bike gets only 35-45mpg. That's pathetic efficiency for such a light vehicle (the motorcycle!).

    To continue the metaphor, people want tough(-looking) vehicles even if they're just dropping off the kids. They want the look so much, they're willing to sacrifice mileage, handling...and several thousand dollars extra, which is why the automakers are obliging. Similarly, motorcycle buyers want manly vehicles, even if the plain, higher-mileage ones are already capable of breaking every speed limit in this country.

    You and I would both like to see more sensible vehicles, but we're unfortunately in the minority. I buy and use sensible vehicles- my bike is small by American standards (I actually wanted a smaller one), and I drove my pickup once in the last month. I think I'm doing my part, but my money can't compensate for the thousands of people who want macho vehicles, EPA be damned. You said it yourself: "Unfortunately, no one rides scooters."


    I'll agree with that. People need to wake up and smell the smog... Start shopping for vehicles a little more responsibly.

    BTW, there's a physical reason why motorcycles and scooters don't get proportionally-better mileage than cars. The average motorcycle (and rider) has a drag coefficient of .7, twice as bad as a modern car, and right up there with pickup trucks. At low speeds, you're right, weight gives the 2-wheeler a distinct advantage. But at highway speeds, air resistance is the dominant loss-factor.

    I don't know if I believe that or not. I find it hard to believe that a motorcycle has that crappy of aerodynamics. We're talking about a vehicle with literally less than 1/3 of the frontal surface area compared to the average sedan.

    Also, if motorcycles had that much drag, they wouldn't be able to go nearly as fast as they can.

  2. Re:Bikes are pathetic for MPG figures. on University of Wisconsin Wins FutureTruck Competition · · Score: 1

    And I suppose your "readily available conventional cars" can do 0-60 mph in 2.8 seconds? That's the oft-quoted GSXR1000 figure. To match it, let alone beat it, you have to go beyond Ferrari, to the McLarens and Vectors with >$250,000 price tags. Meanwhile the GSXR costs $11,000.

    Who needs to do 0-60 in 2.8 seconds on your way to work every day?

    I'm not talking about racing a car and bike, I'm talking about what you drive to and from work every day. How many street bikes actually get noticibly better mileage than a Honda Civic?

    Okay, so that's an extreme example. The Ducati Monster 1000 doesn't even have a multivalve, liquid-cooled engine, yet it turns sub-4-second 0-60 times. Even stock Harleys will outdrag most mass-market cars at an intersection.

    So, do any of those bikes get better than 55mpg? Again, I could care less about racing stats... I'm all about fuel economy of a bike (several hundred pounds) vs. a car (minimum of 2000 pounds, in most cases). Why can't bikes be fast and get good mileage too, compared to your average Honda Civic?

    I think a more apples-to-apples comparison would be a conventional car to a scooter. After all, both are designed to be everyday vehicles, with all the compromises that entails. Then you get your 80 mpg. A hybrid car should be compared to a hybrid motorcycle, and yes they exist (in limited production, which is in line with the relative production quantities of hybrid cars.)

    Scooters are much slower than the average four-door daily commuter, but do get excellent mileage. Unfortunately, no one rides scooters, compared to the number of motorcycles you see on the roads.

    Hybrid motorcycles vs. hybrid cars is fine and dandy. I expect a hybrid motorcycle to get no less than 150mpg with the current technology available. Honda Insight's are good for over 70MPG highway, a bike should easily be double that figure (much less weight).

    Your argument plays directly into the hands of Ford, GM, etc. "Sure we can make significant gains in mileage, but the consumer has largely rejected that. We should not be forced to build something that won't sell." While I agree that Ford, GM, et al are being evasive, and could certainly do more than they're doing, what they are doing is filling a niche. There are people who want SUVs even if they're just going to the mall. They'll pay the price, both financially and chemically.

    You just summed up the attitude of bike makers as well, obviously.

    Most automakers ARE pushing forward with alternatives. Honda and Toyota have done an excellent job with their first mass-produced hybrid automobiles (especially Honda). I have seen no mass-produced motorcycles that are advertised for their fuel economy and emissions.

    Similarly, there are people who want the ability to go 190 mph, even though the odds of that actually occurring are nil. They, too, are putting up legal tender. Same thing with 6-foot-long chrome boats. I don't think race-replicas or custom cruisers make any more sense than SUVs, which is why I don't own any of the three. But no body has yet legislated logic or taste.

    I don't see how any of the above is related to the discussion, but your last sentence I agree with entirely.

  6. I think you are the one who is mistaken on Truck Stops Get Wireless Internet · · Score: 2, Insightful

    True, older diesels had problems running at their low idle setting for extended periods of time. That's why people retrofit a "high idle" switch for extended idling (kept cylinder pressure higher, heat higher, no unburnt fuel issues, no wasted fuel either) on the older diesel engines.

    Newer diesel engines either perform the "high idle" automatically via computer monitoring, and/or come with the manual switch.

    500,000 miles IS a freshly broken in semi engine. My brother just finished hauling freight for a company, using a company truck. His vehicle had over 800,000 miles on it, ran like a champ. My father purchased a semi with just under one million miles on it for use on the farm (hauls grain over the road to elevators/barges).

    Speed limiters are for insurance purposes, nothing more, nothing less. Fast trucks are a liability, especially for a company that hires rookie drivers. They are not there to save fuel, they are not there to prevent idling.

    Also, if you are a company driver (not owner-operator), you aren't going to give a rat's ass about fuel costs, period. You just turn in receipts.

    Both my father and brother own an almost matching set of semis. They're little Ford L9000 semis with a day-cab (no ammenities, not even a passenger seat), and single rear axle. They have slightly different transmissions, but otherwise look and drive the same.

    They're about the smallest tractor you would WANT to drive any amount of distance in.

    They both pull small 22' grain trailers for their farms. They both get around 9-12MPG loaded. Depends where they load up, (river bottoms have shitty inclines that just eat fuel to make it to the paved roads), and where they haul the grain.

    Both trucks only have dual 80 gallon tanks.

  10. Starting kills engines... on Truck Stops Get Wireless Internet · · Score: 1

    ...after they've been shut down for an extended period of time.

    Truckers and other operators of heavy machinery (farmers, construction, etc) let their engines idle because shuting them down and starting them back up is harder on the engines. Oil drains into the pan, more friction on start up than just leaving it idle for a while.

    Also, diesel engines are pretty remarkable when it comes to fuel economy, especially idling. In fact, most diesel engines will actually increase their idle RPM by a couple hundred RPMs during extended idles, because the engine will cool off too much! This results in unburnt fuel that clings to the cylinder walls, some of which will be pulled past the piston rings, causing friction (washing down cylinder walls with diesel instead of oil), and oil contamination.

    Also, some trucks aren't all that reliable when it comes to a cold start-up. Almost every time I've been to a truck stop with the CB turned on, I've heard a trucker asking for someone with a chain to give them a pull so they could start their engine.

    During the winter, letting your diesel engine become cold can really screw you over, especially if you forgot to purchase winterized fuel. Gotta keep the fuel somewhat warm, otherwise it turns to gel when the temps drop into single digits (untreated).

    There are plenty of VERY good reasons those truckers leave their engines idling.
